Description

Packaging container for cold chain {PACKAGING CONTAINER FOR COLD CHAIN}

The present invention relates to a packaging container for a cold chain.

Unless otherwise indicated herein, material described in this section is not prior art to the claims in this application, and inclusion in this section is not an admission that it is prior art.

Cold chain refers to a distribution system that can distribute temperature-sensitive products such as fresh products and medicines while maintaining a constant temperature. As the pharmaceutical and vaccine markets rapidly increase, the cold chain market is also growing exponentially.

In particular, in the case of biopharmaceuticals such as vaccines, there is a risk that their effectiveness may decrease or side effects may occur when exposed to conditions outside a specific temperature range. Accordingly, the demand for cold chain technology is steadily increasing.

In particular, there is an increasing demand for cold chain packaging containers that maintain temperature during transportation.

Cross-border imports and exports of biopharmaceuticals are increasing, and accordingly, demand for packaging containers that maintain temperature using a refrigerant that is relatively inexpensive to produce and easy to dispose of is increasing, rather than packaging containers equipped with batteries.
